This website contains study material prepared by a group of medicos for preparation of NEET PG . Competition for grabbing a seat for medical post graduation is becoming tougher and tougher. This is because in India the ratio of passed MBBS and post graduation seats is quite unfair leading to large backlog of aspirants .Entrance examination which is conducted by NBE is changing its face too frequently . Just a year back it was prometric which changes suddenly to single paper based with negative marks in last year , i.e 2017 . Multiple coching institutes are booming up with a burden of huge fee structure . We to were medicos and we have cracked seats recently . We are here to help our juniors . The main 'mantra' of success is ' Stick to your notes' . WE are trying to generate free online notes which can be printed out easily and of course free of cost .BEST OF LUCK GUYS !!!!
